Grass Fix

Changing Height of Grass:

Dialroom_Center_Landscape > Enable Editing of Contents > Landscape shop > Grass_procedural > Find Displacement node > change 'scale amount' (default 3)
*Note, the smaller the 'scale amount' the shorter the grass will be

Change the Distance the Grass renders:

In the Out Mantra node > Rendering (tab) > Dicing (Sub tab) > Up 'Z-Importance'

*Note, this 'z-importance' should never be bellow 0 and as the number increase it increases the distance from the camera that the displacement is calculated. Also increasing this number dramatically increases render times. So make sure you only increase it as needed and carefully gauge how far away you need the displacement to show up.

What I did to fix the grass in this shot:

Alrighty. For this fix I changed the height of the grass (scale amount) to 1, and upped the z_importance to 6. Please come talk to me if you have any questions about this.
